12316. eel-m1 no. Elmer is eondu d by a pipe 13'into the inlet of a r valve. The latter is arranged to diiis gas or fluid either into the bell 11 pipe 14.- entering the base 15 of the float tank and a stand pipe 16 through whieh a matter of convenient construclion, the stem 10 passes, or into the float tank above tne bell through a pipe 17. As herein iz'idicated, the inletof the casing t'er in a port in the periphery of an apermred vali seat 18 which lies between a pa ii" of exhau. outlets an which the pipes 14 and 17 lead, ,YJGQR the inlet seat and the exhaust 'iectirely. A. stem 21 with parallel and 23 thereon, forms a closure elverasing, that at the upper end of its; throw, as shown in the figure, puts the inlet pipe 13 and tank pipe 17 in comnmniration, and the hell pipe and lower eX- haust opening together, and at the lower end of its throvv reverses those connections. l'loih exhaust openings in the exhaust seats are in constant communication, through a by-pa 241' with an exhaust nipple 25, disrhargin 7 into the. outlet branch 3 through suitably arranged fittings indicated at 26. ut ell valve 2? may be inserted in the .aiter, if desired.

A drum 28 on the master valve, is divided by a movable diaphragm 29, or like INGl'Dl'lfii llll'U fll'] upper chamber vented to the outer air, and a lower closed chamber 30. The in er-valve closure stem 21 is secured by appropriate means to. this diaphragm Q9, and enters the valve casing through. any suitable packing, gland or seal. To insure delicacy of action, the drum standard ill may have an inner tube 32 through which the stem 21 passes freely, Kin im'erted cup 33 on the stem dips into water. oil or other suitable liquid in the tinnular snare around the tube 32, thereby el v .ullv s aling the lower compartment 'alve-seats 19 and 20. The

weight of the stem and closure. A plummet 36 may be added to level the drum if desired.

In order to avoid too rapid movement of the bell 11, the latter is preferably provided with a central well 37 extending nearly to its top with an annular air chamber 38 at its base. A tube 39 extending through the chamber, admits water to the bell from the casing 12, as the bell is depressed, through a flexible pipe or hose 40 having an open ing as at 41, which may be opened to a greater or less degree by a closure indicated,

at 42 that may be adjusted from without the casing. This retards the flow either way so that the movements of the bell may be likewise retarded to prevent violent surging.

A pipe 43 conducts purified gas or liquid under head or pressure, from any convenient source of supply toa branch 4-1 one end of which opens intov the lower compartment of the drum 28 and the other 'extremity of which enters the hydraulic main or conduit 1. If the supply pipes 2 of the latter dip into a liquor seal, as herein indicated, the branch is inserted to the same depth. A restriction 4.5 is placed in the pipe 43, and is so adjusted as to maintain a column of gas or liquid ,in the branch at substantially the pressure in the conduit or main; Consequently any rise in pressure in the main above that for which the apparatus is set, is transmitted to the diaphragm of the master valve which in turn directs the flow into the float tank to depress'the bell and open the regulating valve sufficiently to increase the outflow until the pressure resure.

turns to normal. If the pressure falls, the

diaphragm likewise drops, and the master valve turns the flow of operating fluid into the bell, and the regulating valve closes sufficiently to reestablish the normal'pres- In both cases, the gas or fluid on the low pressure side of the governor is free to escape through the master valve exhaust into the outlet of the main.

In a gas generating or distributing system or apparatus the purified gas is obomitted and the branch 44 is not allowed to dip into a liquid seal in the conduit to be 'tained from some part of the system after it has passed the foul gas conduit or like part to be controlled, a'nd, similarly, in water distribution. it may be supplied from regulated.

Obviously, changes indetails of construction may be made without departing from the spirit of the invention, and I do not care to limit myself to any particular form or arrangement of parts.
